Abstract
A novel method to modify the surface of lanthanum and strontium containing cathode powders before or after sintering by depositing layers of gadolinium doped ceria (GDC) and/or samarium doped ceria or similar materials via atomic layer deposition on the powders. The surface modified powders are sintered into porous cathodes that have utility enhancing the electrochemical performance of the cathodes, particularly for use in solid oxide fuel cells. Similar enhancements are observed for surface treatment of sintered cathodes.
